When washing the throttle, step on the throttle and it doesn't respond.

Mainly considering the throttle and fuel pressure, the throttle is stuck, and there is no fault code, which means it is not a big problem. Wait until the lubricating oil door is cleaned.

If there is no response when stepping on the accelerator, it means that the power of the car is not normal. It may be that the filter of the gasoline pump is dirty, or there may be something wrong with the accelerator pedal, cable and connection with the accelerator. There is no response to the accelerator pedal, which reflects the abnormal power of the car. Engine power is realized by the coordinated combination of intake system, ignition system and oil system. If any component is abnormal, it may cause the engine power to drop, the accelerator pedal to be unresponsive, the car body to shake, and the exhaust gas to smoke.

When stepping on the accelerator, the cable will drive the accelerator, which is the accelerator. There is a position sensor on the throttle. The control unit knows the throttle opening according to the signal of the throttle position sensor, then calculates the corresponding signal voltage, and finally calculates the fuel injection quantity of the vehicle according to the single pressure of the signal.

Therefore, if the throttle position sensor is too dirty or the voltage is unbalanced, the electronic throttle will fail and the throttle will not reach the bottom speed.
